The Jim Bridger Mine is located in southwestern Wyoming, 20 miles north of Rock Springs. Currently, the mine disturbs approximately 100 ac/yr. The mine is situated in the Red Desert, a region used primarily as winter range for sheep. The terrain is rolling, with draws and buttes that are typical of southwestern Wyoming. Precipitation varies between six and eight inches anually. Vegetation is sparse and consists mainly of shrubs and some native grasses, of which saltbush (Atriplex) and sagebrush (Artemesia) are dominant. Four subprojects have been initiated addressing the problems associated with vegetative response to stressed environments, water availability in reclaimed spoils, refaunation dynamics, and topsoil reapplication. A native and a mine spoil site were selected which have a similar slope and aspect. The treatments in the mine spoils include stored topsoil applied over minespoils, native topsoil applied over minespoils (i.e., no storage period), and straw mulch applied over the native topsoil on minespoils.
